We in the UK also don't much like shifting homeless people to low-cost-of-living areas - after all, it cuts them off from what little social support they had, like parents helping with childcare.

So if someone is homeless in London, we pour £££ of taxpayer money into private landlords' pockets.

>To back up your claim of jazz being "European", please source a European that composed with blues scale, jazz chords, and swing before African Americans.

Those jazz chords are descended and altered from traditional european harmony though, themselves, not sole descendants some African musical tradition (which didn't use such harmonies).

As were the instruments themselves (trumpets, trombones, saxophones, pianos, etc.)

Jazz was a mix of African-American vocal music and musical idioms (with a US-localized trhough over African origin) with european harmony, marching band music, and other forms.

This sounds like a great advancement, however an implementation in RDBMS products may be some way away yet - MSSQL uses 8KB pages by default, and I believe (without checking) that most other RDBMSes use at least 4KB. B+ tree index implementations on RDBMS products may be here to stay for a while yet unless these performance issues can be minimised, or unless there is a paradigm shift to use smaller pages - which would have a knock-on effect to query performance unrelated to indexes, such as number of page lookups, increased I/O for non-contiguous page reads...
I can't be the only one who read the title as "Python 2.1" and expected a comparison detailing how recent versions of Python are slower than older ones (Python 2.1 is from 2001).

> Email is centralized because every time I send an email, I'm doing a DNS lookup.

And every time the Signal app connects to its centralized servers, you're doing a DNS lookup too.

> By contrast, if I use a true P2P solution, I never need to do a DNS lookup. My chats in Signal can't be disrupted by a change in MX records.

But Signal isn't a true P2P solution. As your linked description of the Signal Protocol states:

"It does not provide anonymity preservation and requires servers for the relaying of messages and storing of public key material."

> It's like telling people that the WWW is decentralized as long as you use .onion addresses. That's not true because as soon as you get off of public domains, you're not on the WWW anymore.

If you're using HTTP and HTML and hyperlinks and URIs, then you are using the WWW. I suppose you could say that .onion addresses are the Dark Web, but saying they are not part of the web is pointless gatekeeping, like saying that HTTPS sites aren't part of the web because some web clients don't support TLS.

> I don't think you understand this topic.

That makes two of us then.

> There are protocols with encryption schemes built into them. Email is not one of those.

Again, this is an unhelpful observation. HTTP is a protocol that doesn't have encryption schemes built into it, but we didn't decide to throw it away in order to make the web secure. Similarly we don't need to throw away all existing email protocols and clients in order to have secure messaging.

> That is in contrast to Signal Protocol[1], where all clients' E2EE are compatible with each other as long as they're using the same protocol.

No, email is exactly the same as the Signal Protocol in that regard, since all email clients' E2EE are compatible with each other as long as they're using the same (encryption) protocol. The fact that an SMTP server doesn't reject an email that isn't PGP encrypted is a feature, not a bug.
There is a Stonebraker quote somewhere (can't find now) that basically says 'give me the workload and I will build you an optimised database'. The point with building a database enterprise is to build something that is sufficiently general purpose - not just optimised for one workload even if that workload is valuable for one company. In that world, there is only open source. Even snowflake, which is cited as a good example of a new proprietary, is built on FoundationDB and is like a hosted version with lots of bells and whistles. We are building a DB (TerminusDB) and started as prop and we couldn’t see a way to make it work without going open source.

At some point there was also a car company that only sold a single electrical car model, it was pretty expensive and they didn't make that many cars per year, which is not what you would normally call "scalable."

Back to the original goalposts, as far as I know, Waymo is the only company that at this point, does offer a commercial service that's fully driverless. As you point out, they don't cover all of Earth, but neither do any of their competitors. Even Uber and Lyft, with human drivers, don't support all pick up and drop off locations, they only work in certain service areas.
I am approaching it from the scientific standpoint - which of the two measurements is an actual independant variable, and which is an artifact of the measurement? If the planes go twice slower, would their deaths per kilometer stay the same, or would deaths per hour? I am willing to bet it's the latter.

In that case planes have the same chance of failing (mechanically or through human error) as cars do. It is very difficult to increase that safety factor, maybe impossible.

The conclusion to draw from that, is that you can't point at car manufacturers and blame them for producing unreliable / bad quality machines.

On the other hand, measurement per kilometer implies that as a traveller you should use a plane where possible, but obviously they can't replace car in a daily commute.

> It can be channeled for good if consumers inform themselves about what products/services better their lives and actively choose them in the market.

...assuming they're given a meaningful choice in the first place. Consumers choose from what's available on the market, not from some abstract space of possible products. Not only is technology too complicated for the mainstream audience (and products on the market do their best to make everything seem like "magic" that cannot be understood casually by non-specialists), the market doesn't really listen to user feedback anyway, preferring to divine everything from telemetry.

Greed, in general, motivates corporations to make money. Sometimes, providing people with what they demand is the easiest way to profit. Oftentimes, there are better ways. Like investing in marketing to make people demand what you want to provide them. Or scam them through convoluted business models.
What Is Assisted Predictive Modeling and Is It Suitable for Business Users?
It’s more complicated. Apple has the branding to have a higher probability of extracting a higher profit margins at higher volumes compared to other brands, so a different buyer is probably not able to guarantee the level of payments Apple can to TSMC.

I don’t think it’s useful to think of it in terms of Apple needs TSMC more or the other way around. They’re both benefiting quite nicely from the cooperation.

> Site stability and reliability trump how convenient it is for marketing content creators

You’re optimizing for the wrong thing then. Content creation, driving traffic to the site, and converting that traffic is the harder, more important task.

Your role is the easiest, most trivial one.

On the spectrum of engineering problems, I’d place self driving cars and sentient AI somewhere on the right side labeled difficult.

On the left side of the scale, at the far edge labeled easiest, I’d place “keeping a wordpress site online.”

40% of the internet is powered by Wordpress, so I think a few hundred million people have figured it out.

On the other hand, 99% of all websites get little to no traffic. Maybe this is the difficult part you should be optimizing for instead?

It would be pretty straightforward to set up a modern-day version of this low-bloat pickup-ordering:

- Server to process orders and send to restaurant
- Local computer and printer (or fax/vfax setup) at the restaurant

Could probably pair with a static CMS for photographs of the food. Delivery is, of course, a whole different problem to tackle.

The author understates the problem. Many half-baked solutions handle serializing, but don't consider how you're going to deserialize data. And if you do anything with numbers, you may need to guard against intermediate processors that truncate all numbers to 64-bit float accuracy.

I took a shot at it with https://pypi.org/project/json-syntax/ after doing some ad hoc solutions.

My approach was:

1. Don't serialize directly to JSON, but convert to the "jsonic" types.
2. Allow users to pick the rules they need, and make it reasonably easy to create new rules.
3. Generate picklable encoding and decoding functions.

It's worked pretty well for a project that has a very complex set of objects that need to be transmitted via JSON. The main difficulty is that it depends on interrogating Python's type annotations, which were pretty sketchy in earlier versions.
That doesn't change the fact that the external pressure they are designed for is 0 to 1.
All three of these examples (Korea, Vietnam, Afghanistan) were at the time of their "conflicts" impoverished, agricultural economies. Korea, Vietnam and Afghanistan were more important to US allies than to the US. Taiwan, on the other hand, is a modern economy, wealthy and highly integrated with the US economy. Fortunately, all three sides of the Taiwan situation understand this, and because of that, nothing is going to happen (hopefully).
That happens to be better than nearly all their competition.

If that is "tipping silently", then what is the implied default way?
Yes exactly, it's based on CRDTs and there is a strategy out there to mark the entries with a timestamp to figure out which one are the latest. An object may contain many entries and when they are read by the client they are just compared one by one to find the union, or the latest version.

The beauty of it is that the algorithm decide on how much entries to put in objects to ensure that only the data that is changed is sent on the network and compared on the other client. That's why we call it Condensation.

That is in fact, the top comment. Respectfully, I don't think that this is a reduction though. It's a sidestep. I don't mean that the safety (and other ethical) concerns aren't real, and I accept that there are legitimate criticisms of Tesla/Elon... both philosophically and practically.

That is not the actual debate in this article though. It's not the debate between Tesla and Waymo's CEOs. That debate is about the path to a technological goal: actually autonomous vehicles.

The lidar question is closer to the core of the debate, but IMO it's a detail. Here the disagreement might have gotten unproductive. As you say, egos (famously big & nerdy ones) have have been dragged into it.

>> Tesla have made a business decision not to use lidar. It's nothing to do with the maturity of the tech.

I agree with the first and disagree with the second statement. This, IMO, is actually at the core of the debate. In (my assumed version of) Musk's Modus Operandi, technology strategy and business strategy converge much more than in the Waymo/Krafcik MO... They're at opposite ends of the poll.

Business decisions are R&D decisions. Putting things into production is R&D, affects R&D, determines R&D.

In a caricature/model version of the Waymo MO, technology is invented in a research lab. Once it's ready, it can be productized outside of the lab. "Technology" is defined as the core "proof of concept." In the Musk MO, technology is produced in an industry/company. A lab cannot reduce the price of computing by half every 18 months for decades. A lab can't improve the price/weight/performance of batteries to the point of EV viability. It takes an active industry/market to do these things. You need customers. You need commercially scale factories, increasing annual unit production. Etc. Large and increasing numbers of people working on it.

A lot of technology never leaves R&D. Lunar Travel didn't becomes cheaper over time. This confuses people because we expect technology to improve. Doing something people did 50 years ago should be cheap and easy, intuitively. In reality, that momentum is not a guarantee. If no one works on it, it doesn't improve. Software, hardware and such improve at a monstrous pace. But, every year there are way more people working on hardware and software. If the space "industry" had 100X more people working on it compared to 60s, it would have improved to.

I'm not calling Musk's approach superior, but Waymo's is certainly more common. Novelty itself is valuable. It's interesting that we have both approaches at play. n=2, but at least we'll get to see how this plays out.

>Tipping is a cultural thing

True. In UK tipping is seen [in my view correctly] as a reward for good service. So, if a taxi driver or waiter / waitress is especially friendly & helpful, you might leave them a tip.

In other countries, it's seen as almost obligatory. Personal example:

Many moons ago, I was in charge of a large party of students who went to Budapest on an exchange visit. On our first night there, we found a quiet pub near our hostel and settled in for the night. There were only one or two other customers, so we were contributing to them having a really good night, with the kind of takings they'd probably only see on a weekend, usually. We weren't being overly loud or misbehaving, either.

In spite of this, the bar manager and his staff were glaring at us and being really sullen, every time we ordered drinks. I thought it might be because they didn't like 'foreigners' but then one of the locals, who spoke English, told me "They think you're really rude because you're not giving them tips". He went on to explain and it did indeed transpire that the norm in Hungary [or Budapest, anyway] is to give a 10% tip on practically anything you buy, regardless of whether you're served with a smile, or have your food /booze / shopping / whatever slammed down in front of you with barely a glance.

I actually found it quite annoying after a while. If you saw something at XXXX forints, you'd have to mentally add on 10% to the price each time, to work out what you were expected to pay for it. I just thought "If you want 3300 forints for it, then price it at 3300 forints, not 3000!"
On the other hand, we are potentially now closer to our doom than ever before. If we look at all the things, that _in the short term_ improve our lives, but _in the long run_ might seriously impact future generations, then I am no longer so sure about that statement. Zooming out is fine, but not only looking at the past, but also what the future seems to hold, is a worthy perspective to take sometimes.
That's an interesting point. The amount of electronics in cars has increased massively in recent years. They probably see a growing opportunity there because the car manufacturers aren't very good at it.
